The 1LE at least are built for the track...they can take a beating from what I've witnessed (my front alignment didn't even change 1/10th of a degree in any direction even with the off track excursion and 8 x 30min sessions). I literally slid on that aluminum shear plate after my wheel dropped off the back of the curb at probably >60MPH. It did zero other damage to the car for the most part. $300 in parts and 30 minutes to swap it out in the garage. Didn't bend the wheel or even damage the tire.

Some cars need their alignment eccentrics torqued higher than spec to hold [e.g. Miata is a common example], however I haven't found the Alpha platform to be one of those cases.

Marking the adjusters is smart and fairly common with competent mechanics.

I put my car on the alignment rack after a whole season of tracking and through a classic salty Michigan winter and the alignment hadn't moved at all.

Same here minus the winter driving. 2 seasons + now and nothing has moved according to the marked locations. The car tracks true and tire wear is perfect.
If somebody needs to adjust every couple of events may i suggest you change the shop...

I don't have enough miles to bother with checking how my track alignment with new rear bolts has held up yet but the car still tracks straight.

I thought it was only the front bolts that were TTY?

Does anyone know the P/N's for what bolts need to be replaced when doing a 4 wheel alignment?

The fronts are reusable. You want 2 each of these part numbers:

Rear Camber Bolt: 11547215
Rear Toe Bolt: 11611276

Thank you!!

I have to redo my alingment after 1 track day at Sebring... I’m pretty sure it’s out of wack 1/2 way through the day.

My track coach who ran Pirelli World Challenge Series and 5th gen Camaro told me that they made special plates and they deleted the camp Centric Adjusters

I went 54xx miles between alignments with no issues. Not a DD. Having mine done at the local Goodyear shop.
